Description

この発明は、一般的には洗濯乾燥機に関し、特定的には回転ドラム内で衣類の洗濯から乾燥までを行なう洗濯乾燥機に関するものであり、より特定的には洗濯乾燥機において乾燥された衣類に芳香を付与するための装置の改善に関するものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a washing and drying machine, and more particularly to a washing and drying machine that performs washing to drying of clothes in a rotating drum, and more specifically, clothes that are dried in the washing and drying machine. The present invention relates to an improvement of an apparatus for imparting a fragrance to a scent.

従来から、たとえば、特開平２−５７３００号公報（特許文献１）に開示されているように、衣類に紫外線を照射する装置を備えた衣類乾燥機が提案されている。この衣類乾燥機は、衣類を転動する回転ドラムと、このドラム内に熱風を循環する循環経路と、このドラム内に紫外線を照射する照射手段とを備え、照射手段が衣類乾燥工程の減率乾燥工程およびそれ以降の工程の少なくとも一方で照射するように構成したものである。この衣類乾燥機では、照射手段からの紫外線照射を衣類乾燥工程の中で、衣類がほぼ乾いた状態にある減率乾燥工程を主として行うため、紫外線の水分による失活が少なくなり照射手段からの紫外線照射による殺菌が効果的に行われることになるとされている。   Conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2-57300 (Patent Document 1), a clothes dryer having a device for irradiating clothes with ultraviolet rays has been proposed. This clothes dryer includes a rotating drum for rolling the clothes, a circulation path for circulating hot air in the drum, and an irradiation means for irradiating ultraviolet rays in the drum, and the irradiation means reduces the rate of drying the clothes. It is configured to irradiate at least one of the drying step and the subsequent steps. In this clothes drier, the UV irradiation from the irradiation means is mainly performed in the clothes drying process in the rate-decreasing drying process in which the clothes are almost dry. It is said that sterilization by ultraviolet irradiation will be performed effectively.

しかしながら、この衣類乾燥機では、衣類に付着している雑菌の殺菌を行なうために紫外線を衣類に照射するので、高温時に長時間紫外線を照射する必要がある。このため、殺菌効果としては減率乾燥工程以前より乾燥工程終了時まで紫外線を衣類に照射する方法が最も高いが、衣類への悪影響、効果の効率化という点で必ずしも好ましいとはいえないと上記公報に記載されている。   However, since this clothes dryer irradiates clothes with ultraviolet rays in order to sterilize germs adhering to the clothes, it is necessary to irradiate ultraviolet rays for a long time at high temperatures. For this reason, as a sterilization effect, the method of irradiating clothes with ultraviolet rays from before the reduction rate drying process until the end of the drying process is the highest, but it is not necessarily preferable in terms of adverse effects on clothes and efficiency of the effect. It is described in the publication.

また、たとえば、特開２００２−２７５７５６号公報（特許文献２）に開示されているように、繊維製品に日向臭である芳香を付与するために、繊維製品に紫外線を照射する紫外線照射手段を組み込んだ乾燥洗濯機が提案されている。この乾燥洗濯機では、繊維製品に日向臭である芳香を付与するために、回転槽の洗濯物または乾燥する繊維製品に紫外線を照射し、所望により水切り機能を設け、また所望により適宜熱風を与えることによって、洗濯・乾燥を行なうことができると上記公報に記載されている。   In addition, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2002-275756 (Patent Document 2), in order to impart a fragrance that is a sun odor to a textile product, an ultraviolet irradiation means for irradiating the textile product with ultraviolet rays is incorporated. A dry washing machine has been proposed. In this drying washing machine, in order to impart a fragrance that is a sunny odor to textile products, ultraviolet rays are applied to the laundry in the rotating tub or the textile products to be dried, a draining function is provided as desired, and hot air is given as appropriate. It is described in the above publication that washing and drying can be performed.

しかしながら、繊維製品は、多少の水分が含まれている方が乾燥終了時の芳香は強くなるとされており、その効果を示すために長時間にわたって紫外線を照射しながら濡れた布を乾燥した実験結果が記載されている。長時間にわたって紫外線を照射すると、衣類が劣化することはもちろんのこと、芳香においても弊害が生じる恐れがある。
特開平２−５７３００号公報 特開２００２−２７５７５６号公報 However, the fiber product is said to have a stronger aroma at the end of drying if it contains some moisture, and in order to show its effect, the results of an experiment in which a wet cloth was dried while irradiating ultraviolet rays for a long time. Is described. Irradiation with ultraviolet rays over a long period of time may cause harmful effects on aroma as well as deterioration of clothing.
JP-A-2-57300 JP 2002-275756 A

そこで、この発明の目的は、衣類の劣化を抑制することができるとともに、天日干しと同様の香りを衣類に付与することが可能な洗濯乾燥機を提供することである。   Then, the objective of this invention is providing the washing-drying machine which can give the fragrance similar to sun-drying to clothing while suppressing deterioration of clothing.

この発明に従った洗濯乾燥機は、水槽と回転ドラムと照射手段と制御手段とを備える。回転ドラムは水槽内で回転可能に支持されている。照射手段は紫外線を含む光線を回転ドラム内に照射するためのものである。制御手段は、乾燥工程終了時以降に紫外線を含む光線を回転ドラム内に照射するように照射手段を制御する。また、制御手段は、乾燥工程終了時以降でクールダウン後に回転ドラム内の温度を３０℃以上６０℃以下に保った状態で、紫外線を含む光線を回転ドラム内に照射する照射工程を行なうように照射手段を制御する。 The washing and drying machine according to the present invention includes a water tank, a rotating drum, an irradiation means, and a control means. The rotating drum is rotatably supported in the water tank. The irradiation means is for irradiating the rotating drum with a light beam including ultraviolet rays. The control means controls the irradiating means to irradiate the rotating drum with a light beam including ultraviolet rays after the end of the drying process. Further, the control means performs an irradiation process of irradiating the rotating drum with light rays including ultraviolet rays in a state where the temperature in the rotating drum is maintained at 30 ° C. or higher and 60 ° C. or lower after the cool-down after the end of the drying process. Control the irradiation means.

この発明の洗濯乾燥機においては、乾燥工程終了時以降に紫外線を含む光線を回転ドラム内に照射するので、衣類を劣化させることなく、回転ドラム内で乾燥された洗濯対象物に天日干しと同様の香りを付与するのに最適な温度の状態で紫外線を照射することができる。このため、洗濯乾燥機から衣類を取り出したときにまさに天日干しの香りを体験することができる。   In the washing and drying machine of the present invention, since the rotating drum is irradiated with a light beam including ultraviolet rays after the end of the drying process, the laundry object dried in the rotating drum is not sun-dried without deteriorating clothes. It is possible to irradiate with ultraviolet rays at a temperature optimal for imparting the scent. For this reason, when taking out clothes from the washing and drying machine, you can experience the scent of sun-dried.

また、この発明の洗濯乾燥機においては、制御手段は、乾燥工程終了時以降でクールダウン後に回転ドラム内の温度を３０℃以上６０℃以下に保った状態で、紫外線を含む光線を回転ドラム内に照射する照射工程を行なうように照射手段を制御する。天日干しに近似した香りと心地よさを実現するためには、照射工程においてほのかに温かい程度の温度制御が重要である。温度が低すぎると、照射された衣類から香りはかすかに感じられても、それに伴う温かい心地よさを感じることができない。また、温度が高すぎても、揮発する香り成分が飛んでしまい、洗濯乾燥機から衣類を取り出したときに香りを感じることができない。したがって、回転ドラム内の温度を３０℃以上６０℃以下に制御して回転ドラム内の衣類に紫外線を含む光線を照射することにより、天日干しに近似した香りと温かい心地よさを実現することができる。In the washing / drying machine according to the present invention, the control means transmits the light beam including ultraviolet rays in the rotating drum in a state where the temperature in the rotating drum is kept at 30 ° C. or more and 60 ° C. or less after the cooling process is finished after the end of the drying process. The irradiating means is controlled so as to perform the irradiating step of irradiating the laser beam. In order to achieve a fragrance and comfort that approximates the sun, it is important to control the temperature so that it is slightly warm in the irradiation process. If the temperature is too low, even if the scent is felt slightly from the irradiated clothing, the warm comfort associated therewith cannot be felt. Moreover, even if the temperature is too high, the volatile scent component will fly off, and the scent cannot be felt when the clothes are taken out from the washing / drying machine. Therefore, by controlling the temperature in the rotating drum to 30 ° C. or more and 60 ° C. or less and irradiating the clothes in the rotating drum with light rays including ultraviolet rays, it is possible to realize a scent and warm comfort similar to sun drying. .

この発明の洗濯乾燥機においては、制御手段は、紫外線を含む光線を回転ドラム内に照射する照射工程のみを行なうことができるように照射手段を制御することを含むのが好ましい。この場合、乾燥された衣類、または、通常洗濯しないものであっても、回転ドラム内に収容して天日干しと同様の香りを付与することができる。In the washing / drying machine according to the present invention, it is preferable that the control means includes controlling the irradiating means so that only the irradiating step of irradiating the rotating drum with a light beam including ultraviolet rays can be performed. In this case, even dried clothes or items that are not usually washed can be stored in a rotating drum and given the same scent as sun-dried.

さらに、この発明の洗濯乾燥機においては、制御手段は、紫外線を含む光線を回転ドラム内に照射する照射工程を行なうときに、回転ドラムの開口部に対して開閉可能に設けられたドアがロック状態になるように制御することを含むのが好ましい。この場合、使用者、洗濯乾燥機の近くにいる人または近くにある物に紫外線が照射されるのを防止することができる。   Furthermore, in the washing / drying machine according to the present invention, the control means locks a door that is openable and closable with respect to the opening of the rotating drum when performing the irradiation step of irradiating the rotating drum with a light beam including ultraviolet rays. It preferably includes controlling to be in a state. In this case, it is possible to prevent the user, a person near the washing / drying machine, or an object nearby from being irradiated with ultraviolet rays.

この発明の洗濯乾燥機においては、構成部品が紫外線を吸収する材料を含み、紫外線を遮蔽するように構成されているのが好ましい。この場合、構成部品が紫外線によって劣化するのを防止することができ、洗濯乾燥機本体から外部に紫外線が漏れないようにされているので、使用者等、洗濯乾燥機の周りにいる人または置いてある物への悪影響を防止することができる。   In the washing / drying machine according to the present invention, it is preferable that the component includes a material that absorbs ultraviolet rays and is configured to shield the ultraviolet rays. In this case, the components can be prevented from being deteriorated by ultraviolet rays, and ultraviolet rays are prevented from leaking outside from the main body of the washing / drying machine. Can prevent adverse effects on existing objects.

なお、この発明の洗濯乾燥機においては、回転ドラムの開口部に対して開閉可能に設けられたドアに照射手段が設けられているのが好ましい。この場合、ドアを閉じたときに照射手段の照射方向が回転ドラム内に向くように照射手段を配置することができるので、ドアのロック状態等と併せて制御することにより、使用者、洗濯乾燥機の近くにいる人または近くにある物に紫外線が照射されるのを効果的に防止することができる。   In the washing / drying machine according to the present invention, it is preferable that the irradiation means is provided on a door that can be opened and closed with respect to the opening of the rotating drum. In this case, the irradiation means can be arranged so that the irradiation direction of the irradiation means is directed into the rotary drum when the door is closed. It is possible to effectively prevent a person near the machine or an object nearby from being irradiated with ultraviolet rays.

この発明の洗濯乾燥機においては、回転ドラムの外周壁面に向かって紫外線を含む光線を放射するように水槽に照射手段が設けられ、回転ドラムの外周壁面には回転ドラム内に貫通する複数の孔が形成されているのが好ましい。これにより、照射手段として可視光から赤外光までの幅広い波長範囲を含む光源を用いる場合に、その光源から放射される熱線によって回転ドラムの外周壁面が加熱されるとしても、衣類が熱線によって局部的に直接加熱されることはなく、回転ドラム内に貫通する複数の孔から漏れた光が直接、衣類に照射されることによって、回転ドラム内で乾燥された洗濯対象物に天日干しと同様の香りを付与することができる。   In the washing / drying machine according to the present invention, the water tank is provided with an irradiating means so as to emit light including ultraviolet rays toward the outer peripheral wall surface of the rotating drum, and the outer peripheral wall surface of the rotating drum has a plurality of holes penetrating into the rotating drum. Is preferably formed. Thus, when a light source including a wide wavelength range from visible light to infrared light is used as the irradiation means, even if the outer peripheral wall surface of the rotating drum is heated by the heat rays radiated from the light source, the clothing is locally It is not heated directly, and the light leaked from the plurality of holes penetrating into the rotating drum is directly applied to the clothing, so that the laundry to be dried in the rotating drum is similar to the sun drying. A fragrance can be imparted.

以上のようにこの発明によれば、衣類の劣化を抑制することができるとともに、天日干しと同様の香りを衣類に付与することができるので、洗濯乾燥機から衣類を取り出したときにまさに天日干しの香りを体験することができる。   As described above, according to the present invention, it is possible to suppress deterioration of clothes and to impart a scent similar to that of sun-drying to clothes. You can experience the scent of

図示しない制御手段の信号により、モータ４が正逆に回転し、モータ４に直接に接続された回転ドラム３も同様に正逆に回転する。この回転により、回転ドラム３内の内周壁面に固定して設けられたバッフル５が衣類６を持ち上げ、下方に落下させる動作を繰り返すことにより、洗い工程は行なわれる。このようにして、洗い工程が、いわゆる叩き洗い効果を利用して行なわれる。   In response to a signal from a control means (not shown), the motor 4 rotates forward and backward, and the rotating drum 3 directly connected to the motor 4 also rotates forward and backward in the same manner. By this rotation, the washing process is performed by repeating the operation in which the baffle 5 fixed to the inner peripheral wall surface in the rotating drum 3 lifts the garment 6 and drops it downward. In this way, the washing process is performed using the so-called tapping effect.

洗い工程が終了すると、排水ポンプ１１を駆動させて水槽２内の水は排水ホース１２から排出される。その後、すすぎ工程、脱水工程へ移行して洗濯工程が終了する。   When the washing process is completed, the drain pump 11 is driven and the water in the water tank 2 is discharged from the drain hose 12. Then, it transfers to a rinse process and a dehydration process, and a washing process is complete | finished.

次に、乾燥工程の動作について説明する。   Next, the operation of the drying process will be described.

洗濯工程を終了後、乾燥工程に移行し、乾燥運転を開始すると、回転ドラム３の正逆の回転により、衣類６の上下運動による攪拌作用が起きるとともに、循環ファン９と空気加熱ヒータ１０に電力が供給され、空気温度が上昇する。この加熱空気によって加熱された衣類から水分が蒸発して冷却器８内へ流入する。冷却器８内には、対向配置された上方の冷却水入口管１３から冷却水が供給されているので、蒸発した水分が冷却されて凝縮する。この凝縮水は、排水ポンプ１１側へ流れて冷却水と混合して排水される。除湿された空気は再び空気加熱ヒータ１０に還流して加熱される。加熱空気は回転ドラム３内に流入して衣類６を加熱して、衣類６に含まれている水分を蒸発させる。この繰り返しによって衣類６の乾燥が進行する。この乾燥工程で用いられる衣類の加熱源は空気加熱ヒータ１０である。一般的に空気加熱ヒータ１０は、空気循環ダクト内に設けられ、抵抗発熱線を金属被覆して形成されたシーズヒータが用いられる。   When the washing process is completed and the drying process is started and the drying operation is started, the rotating action of the rotating drum 3 causes the stirring action by the vertical movement of the garment 6 and the circulation fan 9 and the air heater 10 are powered. Is supplied and the air temperature rises. Water evaporates from the clothing heated by the heated air and flows into the cooler 8. Since the cooling water is supplied into the cooler 8 from the upper cooling water inlet pipe 13 disposed so as to be opposed, the evaporated water is cooled and condensed. This condensed water flows to the drainage pump 11 side, is mixed with cooling water, and is drained. The dehumidified air is recirculated to the air heater 10 and heated. The heated air flows into the rotating drum 3 and heats the clothing 6 to evaporate moisture contained in the clothing 6. By repeating this, drying of the garment 6 proceeds. The clothing heating source used in the drying process is an air heater 10. Generally, the air heater 10 is provided in an air circulation duct, and a sheathed heater formed by metallizing a resistance heating wire is used.

このようにして衣類６の乾燥が終了した後、すなわち、予熱乾燥工程、恒率乾燥工程、減率乾燥工程、乾燥終了時（空気加熱ヒータ１０をオフにしたとき）を経てクールダウン工程まで行なった後、制御装置により、回転ドラム３の開口部に対してドアユニット７がロック状態にあることが検知され、回転ドラム３内の温度が３０℃以上６０℃以下に制御された状態で、照射光源２１から矢印Ｐで示す方向に紫外線を含む光線が回転ドラム３内で乾燥された衣類６に照射される。照射時間は、回転ドラム３内の温度に応じて５分間から２時間間までの範囲内で調整すればよく、温度が低いほど長く、温度が高いほど短くするのが好ましく、４０℃以上６０℃以下の温度の場合には５分間〜１時間程度が好ましい。   After the drying of the garment 6 is completed in this way, that is, after the preheating drying process, the constant rate drying process, the decremental drying process, and the drying end (when the air heater 10 is turned off), the cooling down process is performed. After that, it is detected by the control device that the door unit 7 is locked with respect to the opening of the rotating drum 3, and the irradiation is performed in a state where the temperature in the rotating drum 3 is controlled to 30 ° C. or more and 60 ° C. or less. A light beam containing ultraviolet rays is irradiated from the light source 21 in the direction indicated by the arrow P onto the clothes 6 dried in the rotary drum 3. The irradiation time may be adjusted within a range from 5 minutes to 2 hours depending on the temperature in the rotary drum 3, and is preferably longer as the temperature is lower and shorter as the temperature is higher. In the case of the following temperatures, about 5 minutes to 1 hour is preferable.

このようにして、乾燥工程終了時以降に紫外線を含む光線を回転ドラム３内に照射するので、衣類６を劣化させることなく、回転ドラム３内で乾燥された洗濯対象物に天日干しと同様の香りを付与するのに最適な温度の状態で紫外線を照射することができる。このため、洗濯乾燥機１００から衣類６を取り出したときにまさに天日干しの香りを体験することができる。   In this way, since the rotating drum 3 is irradiated with light rays including ultraviolet rays after the drying process is completed, the laundry 6 dried in the rotating drum 3 is similar to the sun-dried object without deteriorating the clothes 6. Ultraviolet rays can be irradiated at a temperature optimal for imparting a scent. For this reason, when the clothes 6 are taken out from the washing / drying machine 100, it is possible to experience the scent of sun-drying.

また、天日干しに近似した香りと心地よさを実現するためには、上記の照射工程においてほのかに温かい程度の温度制御が重要である。温度が低すぎると、照射された衣類から香りはかすかに感じられても、それに伴う温かい心地よさを感じることができない。また、温度が高すぎても、揮発する香り成分が飛んでしまい、洗濯乾燥機から衣類を取り出したときに香りを感じることができない。したがって、上述したように回転ドラム３内の温度を３０℃以上６０℃以下に制御して回転ドラム３内の衣類６に紫外線を含む光線を照射することにより、天日干しに近似した香りと温かい心地よさを実現することができる。   In addition, in order to realize a fragrance and comfort similar to sun-dried, temperature control that is slightly warm is important in the irradiation process. If the temperature is too low, even if the scent is felt slightly from the irradiated clothing, the warm comfort associated therewith cannot be felt. Moreover, even if the temperature is too high, the volatile scent component will fly off, and the scent cannot be felt when the clothes are taken out from the washing / drying machine. Therefore, as described above, by controlling the temperature in the rotating drum 3 to 30 ° C. or more and 60 ° C. or less and irradiating the clothes 6 in the rotating drum 3 with light rays including ultraviolet rays, the scent and warm comfort approximate to sun-drying. Can be realized.

洗濯乾燥機においてドアユニットは、従来から、水槽内の水位が一定値を超えていた場合の水漏れ防止、高速回転時における危険防止、乾燥工程時において回転ドラムの内部が一定温度を超えた場合のやけど防止等を目的としてドアロックが働くようになっている。本発明の洗濯乾燥機１００においては、紫外線を含む光線を回転ドラム３内に照射する照射工程を行なうときに、回転ドラム３の開口部に対して開閉可能に設けられたドアユニット７がロック状態になるように制御装置が制御する。これにより、使用者、洗濯乾燥機の近くにいる人または物に紫外線が照射されるのを防止することができる。このようにして照射工程時もドアロックを行い、使用者が紫外線の影響を受けないようにする。ただし、
使用者が一時停止させることにより、照射光源２１の光を消灯し、空気加熱ヒータ１０をオフにする制御を働かせるために、一時停止時のドアロックは解除可能である。その場合、上記の光源と熱源の停止を検知した後、制御装置がドアユニット７のロックを解除するという制御を行なう。 Conventionally, door units in washing and drying machines have been designed to prevent water leakage when the water level in the water tank exceeds a certain value, to prevent danger during high-speed rotation, and when the internal temperature of the rotating drum exceeds a certain temperature during the drying process. The door lock works to prevent burns. In the washing / drying machine 100 of the present invention, the door unit 7 provided so as to be openable / closable with respect to the opening of the rotating drum 3 is locked when performing the irradiation process of irradiating the rotating drum 3 with a light beam including ultraviolet rays. The control device controls so that Thereby, it can prevent that a user, the person who is near a washing dryer, or a thing is irradiated with ultraviolet rays. In this way, the door is locked even during the irradiation process so that the user is not affected by the ultraviolet rays. However,
When the user pauses, the door lock during the pause can be released in order to activate the control to turn off the light from the irradiation light source 21 and turn off the air heater 10. In that case, after detecting the stop of the light source and the heat source, the control device performs control to unlock the door unit 7.

なお、水槽２等、紫外線を遮蔽するために洗濯乾燥機１００の構成部品に適用する構成技術としては、前面ドア７２と同様にして、構成部品に紫外線吸収剤入りのマイクロカプセルをバインダーで全面接着するか、紫外線吸収剤を素材に練り込んで構成部品を成形する方法を採用する。これにより、水槽２等の構成部品が紫外線によって劣化するのを防止することができ、洗濯乾燥機１００本体から外部に紫外線が漏れないようにされているので、使用者等、洗濯乾燥機の周りにいる人または置いてある物への悪影響を防止することができる。   In addition, as a construction technique applied to the components of the washer / dryer 100 such as the aquarium 2 in order to shield the ultraviolet rays, the microcapsules containing the ultraviolet absorber are adhered to the entire components with a binder in the same manner as the front door 72. Alternatively, a method is adopted in which a component is formed by kneading an ultraviolet absorber into the material. As a result, it is possible to prevent the components such as the water tank 2 from being deteriorated by the ultraviolet rays and prevent the ultraviolet rays from leaking outside from the main body of the washing / drying machine 100. Can prevent adverse effects on people in or on objects.

上記の実施の形態の洗濯乾燥機１００では、回転ドラム３の開口部に対して開閉可能に設けられたドアユニット７に照射光源２１が設けられている。これにより、ドアユニット７を閉じたときに照射光源２１の照射方向が回転ドラム３内に向くように照射光源２１を配置することができるので、制御装置がドアユニット７のロック状態等を検知することと併せて制御することにより、使用者、洗濯乾燥機の近くにいる人または近くにある物に紫外線が照射されるのを効果的に防止することができる。   In the washing / drying machine 100 of the above-described embodiment, the irradiation light source 21 is provided in the door unit 7 provided to be openable / closable with respect to the opening of the rotary drum 3. Thereby, since the irradiation light source 21 can be arranged so that the irradiation direction of the irradiation light source 21 is directed into the rotary drum 3 when the door unit 7 is closed, the control device detects the locked state of the door unit 7 or the like. By controlling together with this, it is possible to effectively prevent the user, a person near the washing / drying machine, or an object nearby from being irradiated with ultraviolet rays.

しかし、照射光源２１を含む光照射ユニット２０の取り付け位置はドアユニット７に限定されるものではない。回転ドラム３の開口部から底壁面に向かって衣類６に光線を照射するものではなく、外周壁面に向かって光線を照射するように光照射ユニットを設けてもよい。   However, the mounting position of the light irradiation unit 20 including the irradiation light source 21 is not limited to the door unit 7. The light irradiation unit may be provided so as to irradiate the light toward the outer peripheral wall surface instead of irradiating the clothing 6 with the light beam from the opening of the rotating drum 3 toward the bottom wall surface.

図３は、この発明のもう一つの実施の形態として洗濯乾燥機の概略的な構成を示す側断面図である。   FIG. 3 is a side sectional view showing a schematic configuration of a washing / drying machine as another embodiment of the present invention.

照射光源２１が可視光から赤外光までの波長範囲を含む光線を照射する場合には、照射光源２１は熱線も放射するので、図１に示された洗濯乾燥機１００においては光照射ユニット２０に近い位置にある衣類６が局部的に熱せられることがある。この不具合を解消するために、図３に示すように、洗濯乾燥機２００の主な構成は図１に示したものと同様であるが、光照射ユニット２０が水槽２に取り付けられている。光照射ユニット２０は、紫外線を含む光線を照射するための照射手段である照射光源２１を備えており、水槽２に設置され、回転ドラム３の外周壁面と衣類６とに、矢印Ｐで示す方向に光を直接、照射することができるように構成されている。回転ドラム３の外周壁面には、照射光源２１から放射される光が通過し、衣類６を照射することができるように回転ドラム３の内部に貫通する多数の小孔３２が形成されている。光照射ユニット２０には、照射光源２１から放射された光を回転ドラム３の外周壁面に向かう方向へ反射させるために反射板２２が設けられている。また、光照射ユニット２０には、照射光源２１を洗濯用水と脱水される水とから保護するために光透過性が高い耐熱ガラス板２３が設けられている。光照射ユニット２０は、反射板２２が背面になるように水槽２の外周壁面に固着され、耐熱ガラス板２３が水槽２の外周壁面に密着固定されるようにして、取り付けられている。具体的には、耐熱性（熱絶縁性）と防水性を備えたシール材または接着剤等を用いて水槽２と耐熱ガラス板２３をシールした状態で、光照射ユニット２０が水槽２の外周壁面にビス等で固定されている。   When the irradiation light source 21 irradiates light including a wavelength range from visible light to infrared light, the irradiation light source 21 also emits heat rays. Therefore, in the washing / drying machine 100 shown in FIG. The garment 6 in a position close to may be heated locally. In order to solve this problem, as shown in FIG. 3, the main configuration of the washing / drying machine 200 is the same as that shown in FIG. 1, but the light irradiation unit 20 is attached to the water tank 2. The light irradiation unit 20 includes an irradiation light source 21 that is an irradiation means for irradiating a light beam including ultraviolet rays. The light irradiation unit 20 is installed in the water tank 2 and has a direction indicated by an arrow P on the outer peripheral wall surface of the rotating drum 3 and the clothing 6. It is comprised so that light can be directly irradiated to. The outer peripheral wall surface of the rotating drum 3 is formed with a large number of small holes 32 penetrating into the rotating drum 3 so that light emitted from the irradiation light source 21 can pass through and irradiate the clothing 6. The light irradiation unit 20 is provided with a reflection plate 22 for reflecting light emitted from the irradiation light source 21 in a direction toward the outer peripheral wall surface of the rotary drum 3. In addition, the light irradiation unit 20 is provided with a heat-resistant glass plate 23 having high light transmittance in order to protect the irradiation light source 21 from washing water and dehydrated water. The light irradiation unit 20 is attached to the outer peripheral wall surface of the water tank 2 so that the reflecting plate 22 is on the back surface, and the heat-resistant glass plate 23 is attached and fixed to the outer peripheral wall surface of the water tank 2. Specifically, the light irradiating unit 20 has the outer peripheral wall surface of the water tank 2 in a state where the water tank 2 and the heat-resistant glass plate 23 are sealed using a sealing material or adhesive having heat resistance (thermal insulation) and water resistance. It is fixed with screws.

上記のように構成された光照射ユニット２０を点灯することにより、回転ドラム３の外周壁面が加熱されるとともに回転ドラム３の外周壁面から内部に貫通するように開口した多数の小孔３２から漏れた光が直接、衣類６に照射される。これにより、回転ドラム３内で乾燥された衣類６に天日干しと同様の香りを付与することができる。   By illuminating the light irradiation unit 20 configured as described above, the outer peripheral wall surface of the rotating drum 3 is heated and leaks from a large number of small holes 32 that open from the outer peripheral wall surface of the rotating drum 3 to the inside. The garment 6 is directly irradiated with the light. Thereby, the fragrance similar to sun-drying can be provided to the clothes 6 dried in the rotating drum 3.

なお、上記の洗濯乾燥機１００または２００において、制御装置が、紫外線を含む光線を回転ドラム３内に照射する照射工程のみを行なうことができるように照射光源２１を制御するように構成されていてもよい。これにより、すでに乾燥された衣類、または、通常洗濯しない衣類等であっても、回転ドラム３内に収容して天日干しと同様の香りを付与することができる。   In the washing / drying machine 100 or 200 described above, the control device is configured to control the irradiation light source 21 so that only the irradiation step of irradiating the rotating drum 3 with the light beam including ultraviolet rays can be performed. Also good. As a result, even clothes that have already been dried or clothes that are not usually washed can be accommodated in the rotating drum 3 and given the same scent as sun-dried.

図４は、光照射ユニット２０の構成例を示す概略的な側断面図（Ａ）と正面図（Ｂ）である。正面図（Ｂ）では、耐熱ガラス板２３を取り外した状態を示す。   FIG. 4 is a schematic side sectional view (A) and a front view (B) showing a configuration example of the light irradiation unit 20. In the front view (B), the heat resistant glass plate 23 is removed.

図４に示すように、照射光源２１の裏面には光反射効率の高い反射板２２が設けられ、光照射面には光透過率の高い耐熱ガラス板２３が設けられている。耐熱ガラス板２３で照射光源２１を覆うとともに、光照射ユニット２０の筐体は金属製の防水ケースからなる。防水ケースはステンレス鋼、亜鉛めっき鋼板等の一般的な金属板で形成すればよい。このようにして、光照射ユニット２０は洗い、すすぎ、脱水工程で飛散する水を遮蔽することができる防水性のユニット仕様になっている。図４に示す構成例では、照射光源２１はリング状の形態を有するが、取り付け面積を低減するために直線状の管のものを用いてもよい。光の吸収がほとんどないため、反射板２２の材質はアルミニウムを採用するのが最も好ましく、金属光沢のあるステンレス鋼等を用いてもよい。耐熱ガラス板２３の材質は、耐熱性と熱衝撃性の高い材料であればよく、たとえば結晶性ガラスを採用するのが好ましい。   As shown in FIG. 4, a reflection plate 22 having a high light reflection efficiency is provided on the back surface of the irradiation light source 21, and a heat-resistant glass plate 23 having a high light transmittance is provided on the light irradiation surface. The irradiation light source 21 is covered with a heat-resistant glass plate 23, and the housing of the light irradiation unit 20 is made of a metal waterproof case. The waterproof case may be formed of a general metal plate such as stainless steel or galvanized steel plate. In this way, the light irradiation unit 20 has a waterproof unit specification that can shield water scattered in the washing, rinsing, and dehydration processes. In the configuration example shown in FIG. 4, the irradiation light source 21 has a ring shape, but a linear tube may be used to reduce the mounting area. Since light is hardly absorbed, it is most preferable to use aluminum as the material of the reflecting plate 22, and stainless steel having metallic luster or the like may be used. The heat-resistant glass plate 23 may be made of a material having high heat resistance and high thermal shock, and for example, crystalline glass is preferably employed.

本発明の一つの実施の形態として図１に示された洗濯乾燥機１００を用いて乾燥運転を行なった一つの実験結果として測定された温度データを図２に示す。実線は回転ドラム３からの排気温度を、点線は回転ドラム３からの排気温度と冷却水温との差を示している。乾燥工程は通常、予熱乾燥工程ａと恒率乾燥工程ｂと減率乾燥工程ｃとに分けられ、終了検知で判断した乾燥終了時点ｄから、空気加熱ヒータ１０をオフにして使用者が安全に衣類６を取り出すことができるようにクールダウンｅを行なう。クールダウン終了時でも、回転ドラム３からの排気温度はまだ６０℃以上である場合も少なくない。したがって、天日干しに近似した香りと温かい心地よさを実現するためには、乾燥工程中やクールダウン時に照射光源２１から光線を衣類６に向けて照射するのは好ましくない。   FIG. 2 shows temperature data measured as a result of an experiment in which a drying operation was performed using the washing / drying machine 100 shown in FIG. 1 as one embodiment of the present invention. The solid line indicates the exhaust temperature from the rotating drum 3, and the dotted line indicates the difference between the exhaust temperature from the rotating drum 3 and the cooling water temperature. The drying process is usually divided into a preheating drying process a, a constant rate drying process b, and a decreasing rate drying process c, and the user can safely turn off the air heater 10 from the drying end point d determined by the end detection. Cool-down e is performed so that the clothes 6 can be taken out. Even at the end of the cool-down, the exhaust temperature from the rotary drum 3 is often 60 ° C. or higher. Therefore, in order to realize a scent similar to that of sun-drying and warm comfort, it is not preferable to irradiate the clothing 6 with light from the irradiation light source 21 during the drying process or during cool-down.

これを証明するために、殺菌ランプからの光線を木綿タオルに照射した場合の温度と時間による芳香の官能試験結果を表１に示す。   In order to prove this, Table 1 shows the results of sensory test of aroma according to temperature and time when a cotton towel is irradiated with light from a sterilizing lamp.

Figure 0003739377
この殺菌ランプから出射される光線は２６０ｎｍ付近の波長にピーク強度を有し、実験の都合上、出力が１５Ｗのものを使用した。しかし、実際の洗濯乾燥機に搭載するランプとしては、３００ｎｍ以上の波長にピーク強度を有する光線を出射するブラックライトや捕虫器用ランプでもよく、また出力が４Ｗ程度の小型のものでもよい。
Figure 0003739377
 A light beam emitted from the sterilizing lamp has a peak intensity at a wavelength near 260 nm, and an output of 15 W is used for the convenience of the experiment. However, the lamp mounted on the actual washing / drying machine may be a black light or a trap for catching insects that emits light having a peak intensity at a wavelength of 300 nm or more, or a small lamp with an output of about 4 W.

表１に示される官能試験結果において、＋は外に干した香り、＋＋＋は天日干しに近い心地よい香り、△はやや辛みのある香りを示している。この結果より、温度が３０℃では外に干した香りはするが、何か足りない感じがする。また、温度が６０℃では、短時間で香りを達成するが、香ばしいような辛い香りが生じるまでの時間も短い。したがって、照射する温度条件は３０℃から６０℃までの範囲が好ましいといえる。ブラックライトや捕虫器用ランプを用いても同様のことがいえるが、殺菌ランプに比べて、天日干しに近い心地よい香りに到達するまでの時間が長く(３０分〜１時間)、やや辛みのある香りに到達するまでの時間も長い(２時間〜３時間)。   In the sensory test results shown in Table 1, + indicates a scent dried outside, +++ indicates a pleasant scent similar to sun-dried, and Δ indicates a slightly spicy scent. From this result, although the temperature is 30 ° C., the scent is dried out, but it feels something is missing. Moreover, at a temperature of 60 ° C., the scent is achieved in a short time, but the time until a spicy scent is generated is also short. Therefore, it can be said that the temperature condition for irradiation is preferably in the range of 30 ° C. to 60 ° C. The same can be said with a black light or insect trap lamp, but it takes a longer time (30 minutes to 1 hour) to reach a pleasant scent close to the sun than a sterilization lamp, and a slightly spicy scent. It takes a long time to reach (2 to 3 hours).

以上の実験結果に基づいて、乾燥工程中とクールダウン中では、表１に示すように天日干しに近い心地よい香りを得るための最適温度帯(３０〜６０℃)の状態に回転ドラム３内を保つことができないため、本発明では、クールダウン後に回転ドラム３内を最適温度帯(３０〜６０℃)に保って、光を照射する照射工程を設ける方式をとり、乾燥工程終了時以降のわずかな時間に紫外線を含む光線を照射することにより、取り出すときの衣類に天日干しの心地よさを実現することを可能にした。   Based on the above experimental results, during the drying process and during the cool-down, as shown in Table 1, the inside of the rotary drum 3 is brought into an optimum temperature zone (30 to 60 ° C.) for obtaining a pleasant scent close to sun-drying. In the present invention, after the cool-down, the rotating drum 3 is kept in the optimum temperature zone (30 to 60 ° C.) and an irradiation process for irradiating light is provided. By irradiating with light including ultraviolet rays at a reasonable time, it became possible to realize the comfort of sun-drying for clothes when taking out.

以上に開示された実施の形態と実施例はすべての点で例示であって制限的なものではないと考慮されるべきである。本発明の範囲は、以上の実施の形態と実施例ではなく、特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての修正や変形を含むものである。   It should be considered that the embodiments and examples disclosed above are illustrative and non-restrictive in every respect.
